FT232RNL-REEL | FTDI

USB to serial UART interface, FT232RNL-REEL, FTDI

The FT232RNL is a USB to serial UART interface with optional clock generator output, adding two new functions compared with its predecessors, effectively making it a “3-in-1” chip for some application areas. The internally generated clock can be brought out of the device and used to drive a microcontroller or external logic. A unique number is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied.

Features

• Single chip USB to asynchronous serial data transfer interface
• Entire USB protocol handled on the chip - no USB-specific firmware programming required
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
• Fully assisted hardware or x-on / x-off software handshaking
• Data transfer rates from 300 baud to 3 megabaud (RS422 / RS485 and at TTL levels) and 300 baud to 1 megabaud (RS232)
• In-built support for event characters and line break condition
• New configurable CBUS I/O pins
• Auto transmit buffer control for RS485 applications
• Transmit and receive LED drive signals
• FIFO receive and transmit buffers for high data throughput
